Subject: [PATCH V4 6/8] IB/rdma_cm: TOS <=> UP mapping for IBoE
Date: Thu, 29 Mar 2012 17:03:36 +0200 [thread overview]
Message-ID: <1333033418-1669-7-git-send-email-amirv@mellanox.com> (raw)
In-Reply-To: <1333033418-1669-1-git-send-email-amirv@mellanox.com>
Both tagged traffic and untagged traffic use tc tool mapping.
Treat RDMA TOS same as IP TOS when mapping to SL
